MACHINE-TABLE.

SPECIFICATION. forming part of Letters Patent No. 299,697, dated June 3,1884.

Application filed September 7, 1E3. (No model.)

To all whom it may concern:

Beit known that I, JOHN J. SULLIVAN, of Green Point, in the county ofKings and State of New York, have invented a new and useful Improvementin Receiving-Tables for Saw-Ta bles, of which the following is aspecification.

In sawing box-boards to reduce them to uniform sizes for box-making andother purposes7 a boy is usually employed to stand at the back of eachsaw-table to draw forwardthe boards as they leave the saw and to pilethem up. The services of the boy are necessary to prevent the pieces ofboard frombeing thrown back by the rapidly-rotating saw, and thusinjuring, orperhaps killing, the Sawyer, and also to pile up and takeaway the sawed boards.

The obj ect of my invention is to dispense with the services of a boy ateach saw-table.

' To this end the invention consists in the combination, with acircular-saw table, of a pair of holding and drawing rolls, which areadapted to grasp a board before it leaves the saw and to draw itforward, a rising and falling receiving-table arranged at the end of thesaw-table, a counterbalance-weight connected with the saidreceiving-table, and a number or series of supplemental weights, whichare arranged to be picked up by the ascending counterbalanceweight asthe receiving-table descends by the increasing weight of boards receivedupon it.

The invention also consists in novel combinations of parts, hereinafterdescribed, and referred to in the claims.

In the accompanying drawings, Figure l is a vertical section of aportion of a circularsaw table and a receiving apparatus embodying myinvention, the receiving-table being in its highest position. Fig. 2 isa rear view of the apparatus, with the receiving-table in the sameposition as in Fig. l; and Fig. 3 is a vertical section similar to Fig.l, except that the receiving-table is loaded and in a depressedposition.

Similar letters of reference designate corresponding parts in all thefigures. A designates the saw-table, and B the saw Working therein androtated by a belt, B. At the end of the saw-table A are standards orframes C, which at their upper ends carry the bearings for a pair ofholding and drawing 5o rolls, D D, which are geared together by pinionsa, and one of which carries a pulley, b, which receives a driving-belt,b. g

E designates the receiving-table proper,

which is arranged at the end of the sawtable 55v A and beyond the rollsD. The said receiving-table E is secured on a supporting-frame,

E', which is between the standards C, and is fitted to guides d on theinner sides of the standards. The said frame LE has a down- 6owardly-projecting rod, FP, working through a stationary guide, e, at thebase of the machine. The severa-l guides described serve to main-` tainthe table E in a horizontal position as it rises and falls. To the frameE of the table E is connected a cord, chain, yor like device,

f, ,which is carried upward over a pulley, g, and thence downward to acounterbalancing- Weight, F, which is guided in standards or posts G,and which is heavy enough to main- 7o tain the table E in the elevatedposition shown in Figs. 1 and 2 when no weight is on it.

F F2 designate supplemental weights, which rest in supports h, attachedto the standards G, and at different heights. ber of these supplementalweights, supported at different heights, may be employed, and they willbe picked up, one after the other, by the main weight F as it ascends.Before the boards or pieces H leave the saw the rolls D 8o grasp themand draw them forward onto the receiving-table E, and after three orfour or more have accumulated thereon the receivingtable descends.' Asthe weight of boards on the receiving table increases, the weight Ffirst 8 5 picks up the supplemental weight F', and afterward the secondweight, F2, and so on with the Y other weights, if others be used. Fromtime to time the pile of boards is taken from the receiving-table, andthe latter then rises t0 its 9o original position. The rolls -D preventthe boards Aor pieces from being thrown-back by the rapidly-rotating sawas they leave the saw, and while the sawyer is presenting or movinganother board against the saw. 95

I do not claim, broadly, the rolls D in com bination with a saw, butonly desire to include in my invention the combination of the said Anydesired numy y rolls with the rising and falling receiving-table andwith the saw-table.

YVhat I claim as niy invention, and desire to secure by Letters Patent,is-

l. The combination, with a circular-saw table, of a pair of holding` anddrawing rolls which are adapted to grasp a board before it leaves thesaw and to draw it forward, a rising and falling receiving-tablearranged at the end of the saw-table, a counterbalance-Weight connectedwith the said reccivingtable, and a number or series of supplementalweights which are arranged to be picked up by the ascendingeounterbalance-wcight as the receiving table descends by the increasingWcight of boards received upon it, substantially as and for the purposeherein described.

2. The combination of the saw or other table', A, the standards C, thereceiving-table E, fitting between and guided by the standards C, thecounterbalancing-weight F, connected Wit-l1 said receiving-table, one ormore supplemental weights, and supports h for the supplemental Weights,at dii'ercnt heights, substantially as and for the purpose described.
